Textil och glas ? ett universum

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

Energieffektivisering på Skutskärs Bruk : Varvtalsstyrning till utvalda pumpenheter på Blekeri 4

In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.

Cyklisters situation på 2+1-vägar

In this report the situation for cyclists on 2+1-roads is analysed and studied. Theseroads are often the old 13-meter roads that have been changed into 2+1 to increasethe security. Two road sections outside Motala in Sweden has been deep studiedand analysed. The different parts in the planning process show how the progressgoes. To begin with the change should be within the old 13 meters but after thepilot study was circulated for comments the result became a broadening to 13,75and 14,00 meters.

Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Elevers föreställningar om vattnets kretslopp och växtens liv : Har eleverna tillräcklig kunskap inom dessa områden för att diskutera hur miljöförstörning påverkar vatten och växter?

The purpose of this investigation is mainly to study if pupils have enough knowledge concerning the water cycle and the life of the plants?, and what kinds of household word they have, to discuss pollution within these areas. I also studied how the pupils? knowledge are holding up against what the course-plans says, since it have come to light by other investigations that knowledge are insufficient within the nature-oriented (No) subject in school.The survey has carried out on 28 pupils in a 5th grade, with help of a questionnaire survey. Their teacher has been interviewed and I have studied their local course-plans and also the pupils? schoolbooks in No.The result of the questionnaire survey indicates that the pupils had insufficient knowledge within the areas of plants? life and pollution, something their teacher had a presentiment about.The conclusion is that they need to go out more often in the nature and see how the plants and the environment are affected by different factors.

GRÖN FLAGG : Miljöarbete i förskolan

The aim with my work is to get a deeper knowledge about the preschool's views of environmental work. I also want to examine how the preschool teachers along with the children work with the project Green Flag in the preschool. I have used structured interview with two teachers in a preschool that works with Green Flag. Green Flag is an environment certification and is an evidence on that one works daily with a document aimed environmental work along with the children. I have found out that each year they work with different themes within Green Flag.

Betalningstider : En statistisk undersökning om företags faktiska kundkreditdagar.

Account receivables tie up large amounts of capital in. Various reports show that the actual time for customer to pay their invoices is getting longer. This is a problem both from a society and a business economic perspective. The purpose of the essay is to find out if Swedish companies have longer credit days than normal contractual terms of payment and if so, can the business cycle or the geographical distribution of sales have an impact and does it make a difference if the companies have an active monitoring of the actual customer credit days. To answer this, we studied 12 listed companies in four different sectors between the years 2000-2008. In the analysis, we reason about the results of the study and how the various factors may have influenced the outcome.

Riskkapitalbolags inverkan på risk för finansiell kris i portföljbolag: En studie av 53 transaktioner i tillverkningsindustrin

The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.

Elproduktion med ORC-teknik ombord på fartygsserien MK II.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

Konstruktion av en autonom vindstation

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

KOMMUNALSKATTER OCH KONJUNKTUR

Fiscal policy and its consequences have attracted much attention on both academic and societal level, in Sweden and elsewhere. However, the dependence between fiscal policy on municipality level and business cycles has only recently sparked a debate among Swedish economists. Studies point out that a law which came to force in 2000, balanskravet, may have caused municipalities to lower expenditures, alternatively raising taxes, during recessions. This thesis examines how the level of municipality taxes depends on business cycle fluctuations and the impact that balanskravet has had on this correlation. We employ econometric regressions, with annual data covering the period 1980-2014, to enable an analysis of the dependence between taxes and business cycles, both before and after the introduction of balanskravet.

Biologin hos svenska Lilioceris arter och åtgärder för att begränsa deras skadeverkningar :

Summary The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years. The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies. Lilioceris species overwinter normally as pupae in the soil under the host or close by. Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining. My own observations include different treatments of both lily foliage and of the leaf beetle.

Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :

Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse. This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.

Marknadens inverkan på behovet av företagsstöd - en studie av sex uppstartsföretag

In efforts to strengthen local economies, business development programs are often a way in which governmental organizations and state affiliates try to facilitate innovation and successful entrepreneurship. There is a mutual interest from both the public and private sector that these funds are put to good use. Extensive research has been conducted with the focus of the general effect of public support programs. However, not much research has been done on what external factors affect the situation for receiving businesses. This study attempts to examine whether one specific such factor, the level of maturity on the markets that the recipients operate in, has a discernible effect on the needs for different types of entrepreneurial support.
